Characteristics of sound field measurement using a laser Doppler vibrometer (LDV) have been investigated with the aim of evaluating the applicability of the optical measurement method of sound fields to a diagnostic technique for equipment abnormality in high radiation environments. Important aspects of sound measurement using a LDV are discussed based on its dependence on optical path length and sound frequency in terms of anomaly detection and diagnosis in terms of anomaly detection and diagnosis.
